The rover was ~120 m shy of a marathon at this location. If you follow the dark streak heading southwest, you’ll see two ‘fresh’ craters of equal size. The ‘finishing line’ was just above them.

good to see this. Musk is clearly getting visibly angry at the rising awareness of how many hundreds of thousands of people his DOGE wilding spree has already killed, millions more if this stays in place into the future. Everyone can participate in spreading the word about all the blood on his hands

I do hope @royalsociety.org are paying attention. In fact, I’m sure they are, but they don’t care.

Fun fact: This is how we produce the overhead navcam ortho images. No nerd shit with math and algorithms. Only rad jumps for this rover!

Coryn Bailer-Jones is one of the main Gaia Mission astronomers. His huge table of Bayesian distance estimates are what most researchers use to convert Gaia parallaxes into distance. And now he has written a textbook on interstellar travel.

The Arrakihs mission has been adopted as ESA's next F-class mission, with an expected launch in 2030! It will look at the low surface brightness outskirts of 80 Milky Way-like galaxies. www.esa.int/Science_Expl...

This is a pogrom, incited and instigated by Elon Musk. This is now the second set of pogroms incited by Elon in the UK in 2 years.

For Artemis III SpaceX won't deliver the planned Lunar Starship, instead they'll use a regular V3 starship with an extra docking adapter.

There are almost no crustaceans in the deep ocean. Not because they would get crushed, but because they would DISSOLVE. The cold & high pressure cause changes to water that make it very corrosive to calcium carbonate shells. But there's one crustacean who solves this problem with ALUMINUM ARMOR.

Your child’s drawing on a real rocket? 🤩 Kids up to 12 can create a space-inspired drawing for a chance to see it printed on the fairing of Ariane 6, for the launch of Plato next year. ✨ Submit by 1 July 2026! More info 👇 www.esa.int/kids/en/thin...

Are you feeling the heat too?🥵 A heatwave is driving temperatures far above average across much of Western Europe and the UK, with record May temperatures reported in several countries. This map shows land surface temperatures across Europe, using Copernicus Sentinel-3 data from 26 May 2026.

Fun to watch Tesla and Musk fan accounts call my reporting wrong, only for them to ask Grok and have the AI tell them that I'm right.

Would like to highlight that NASA plans to re-open the contract management bid for JPL in 2028 when the current prime contract with Caltech expires. This means they are looking at *taking JPL’s management out of Caltech’s hands*, a disastrous decision likely so a billionaire can profit from it.

Incredible

Anyone that tells you SpaceX is wasting money building Starship has no idea about how much money is being spent on AI development.

SpaceX was making money from launching rockets. Then Elon Musk decided to waste it by littering the sky with Starlinks and blowing up Starships; when he was not off causing the deaths of hundreds of thousands of people by interfering with USAID. www.wsj.com/business/spa...

What a launch! Great start to our mission. Now sone days raising the orbit before science commissioning can begin!

Two new facts stand out: 1. 85% of hallucinated citations in preprints are also in the subsequent journal version (thanks, peer review!) 2. Fake cites more likely to use the names of (male) scholars who are already highly cited, creating a fake-citation Matthew effect. arxiv.org/abs/2605.07723

😱 We still have some ESA Bulletins going back to the 1980s! Surprise the space geek(s) in your life with an issue from their birth month/year. Just drop the month/year you’re interested in in the comments and, if we have it, we’ll mail it to you free of charge 😎👍

assuming it holds up to scrutiny, this paper by ko arimatsu et al. out yesterday reporting the discovery of an atmosphere around a kind of run-of-the-mill trans-neptunian object is genuinely one of the more surprising and exciting discoveries in years in my book www.nature.com/articles/s41...

We have an *extremely* important announcement to make. From Wednesday, we will be launching our puffin live cam, coming to you from the Farne Islands. So you can watch puffins all day long. In celebration, please enjoy this clip of puffins being really busy for 39 seconds straight.

#ArtemisII My latest cartoon for @newscientist.com

Time to take a dive into the science from humanity's three asteroid sample return missions: Hayabusa, Hayabusa2, and OSIRIS-REx! 🪨🛰️🔭 Written for non-geophysicists (like me!), and those new to the field who don't yet ask to "pass the halite" at the dinner table 🧪, this is my review journal paper:

I genuinely think some people do not want to look this in the eye/think about it because it is so awful. We wrote what I thought was a pretty eye-opening story about all this and I was surprised by the lack of engagement tbh

I got to see Dragonfly in the APL cleanroom, and she’s beautiful! And BIG. No photos from the cleanroom, but here’s a full-scale test article in the lobby of Building 200 at APL. 😍

Best thing I’ve gotten to do this month was interview Expanse writers Daniel Abraham and Ty Franck about how speculative biology, the politics of academia and a Bible story all shaped their latest novel, The Faith of Beasts. Check it out! www.importantnotimportant.com/p/the-expans...

Science Committee Democratic Staff Report Reveals Details on NASA’s Illegal Implementation of Trump’s FY2026 Budget Request Without Congressional Approval. democrats-science.house.gov/news/press-r...

Just FYI, nothing in this arXiv submission is real or true. This is completely misunderstanding the NISP instrument onboard #Euclid and then creating AI slop "results" based on that. arxiv.org/abs/2604.02726

Seems to be a busy day on Bluesky, so if I did a Kickstarter, like one of the following two topics.

The FY 2027 NASA budget request hides its science cuts by omitting mission names instead of explicitly zeroing them out. We did the work and found 54 missions cancelled in this proposal. This is another extinction-level event for NASA science. Full list: planetary.org/save-nasa-science

Hello, I made you a feed of your cats watching the Artemis II splashdown bsky.app/profile/did:...

Ramona has become a big space fan. Welcome home, Artemis II. What an incredible quest.

The Lunar flyby happens today. Follow @barbylon.bsky.social for an insider view from the #ArtemisII Lunar Science Team! 🧪🔭🌘🚀

Errrr, I seem to be having a problem with a couple of my Easter eggs…

It’s 03:30 for me, so how about a review of the sleep config of the Orion cabin? This is a fairly straightforward config & the crew has some flexibility for how they want to arrange things. Typically crew sleep is a cameras off period, but I’m sure they’ll give folks a peek at some point.

“Vice President JD Vance thinks aliens are visiting earth and that they are Demons” is the most “I wish Carl Sagan were alive” moment I’ve had in a while.

I am apparently locked out of my main bsky account @bowlerhatscience.org (permanently?), so I've made this alt. I can prove it's me but I really don't wanna *have* to do it.

Delighted to see our WISPIT team announce the second directly imaged exoplanet from the WISPIT 2 system! Led by Chloe Lawlor (Galway) with Richelle van Capelleveen (Leiden), we also have a spectrum of the inner, more massive planet, showing carbon monoxide features. ☄ #exoplanet #astrodon

When you offer charitable services or give to a cause, you don't usually have strings attached. It's done out of kindness and concern. I guess someone with more money than some nations (and complains that money hasn't made him happy) has yet to figure that out.

Have to thank @beamjockey.bsky.social for reposting this and putting this on my radar. This year's LPSC seems like it's the proverbial "canary in a coal mine" for the state of Planetary Science here in the US. This SHOULD be a very vibrant time, but instead it seems moribund.

So, what do you think of Project Hail Mary?

Hubble unexpectedly catches comet breaking up ☄️ Comet K1 fragmented into at least four pieces while the NASA/ESA Hubble Space Telescope was watching. The odds of that happening while Hubble viewed the comet are extraordinarily miniscule! 🔗 www.esa.int/Science_Expl... @science.esa.int @stsci.edu

none of our trail or process cameras captured the meteor this morning but Nicole did offer this artist rendering.
